Description of key information

Evaluation was made based on a study carried out according to OECD Guideline 121 (Estimation of the Adsorption Coefficient (Koc) on Soil and on Sewage Sludge using High Performance Liquid Chromatography (HPLC)) and EU Method C.19 (Estimation of the Adsorption Coefficient (KOC) on Soil and Sewage Sludge Using High Performance Liquid Chromatography (HPLC)).  The Koc and log Koc value of the major component in Small Vinyl Ester based on soil-absorption-reference data is 2.4 E+4 and 4.38, respectively. 

Key value for chemical safety assessment

Koc at 20 °C:
24 000

Additional information

It is found that Koc is 24000, and log Koc is 4.38 both at 35 °C. The high values indicate that Small Vinyl Ester will bind tightly to soils and sediments and thus, reduce overall exposure potential.
